Abstract
An analog-to-digital converter including a first module of the type having a series of processor stages, each of the stages performing two conversions of the signal output by the preceding stage, firstly an analog-to-digital conversion and secondly a digital-to-analog conversion, followed by subtracting the signal obtained from the output signal of the preceding stage to provide the analog output signal of the stage. The first module further assembles together the signals digitized by each stage (S , . . . , S ) so as to provide an assembled digital signal (S (nT) which represents the input signal (e(nT) of the converter in digital form. The converter further includes a &Dgr;&Sgr; modulator which digitizes the output signal (b(nT)) from one of the stages, the resulting digitized signal being subtracted from the assembled digital signal (S (nT)
